Rochelle wakes from cryostasis to take up her role as engineer on the colony ark, Calypso. But she finds the ship has transformed into a forest, populated by the original crew’s descendants, who revere her like a saint.

She travels the ship with the Calypso’s creator, the enigmatic Sigmund, and Catherine, a bioengineered marvel who can commune with the plants, uncovering a new history of humanity forged while she slept.

She discovers a legacy of war between botanists and engineers. A war fought for the right to build a new Earth – a technological paradise, or a new Eden in bloom, untouched by mankind’s past.

And Rochelle, the last to wake, holds the balance of power in her hands.
